Converting from Degree (°) to Radian (rad) | Angle

What is Degree (°)

Degree (°) is a unit of measurement for angles. A full circle is divided into 360 equal parts, and each part is represented by 1 degree.

What is Radian (rad)

Radian (rad) is another unit of measurement for angles, commonly used in mathematics and physics. It represents the angle subtended by an arc on a circle that is equal in length to the radius of the circle.
